C70 Combination Air Valve with Surge Protection
Bermad C70-SP is a high quality combination air valve (approved to AS4956 and appraised by WSAA) for a variety of water networks and operating conditions. It evacuates air during pipeline filling, allows efficient release of air pockets from pressurized pipes with a surge protection device minimising potential water hammer, and enable large volume of air intake in the event of network draining. With its advanced aerodynamic design, double orifice anti-slam/slow closing device, this valve provides excellent protection against air accumulation, vacuum formation and pressure surges, with improved sealing in low pressure conditions. The valve minimizes water spraying during air release.
